The Prehistory of P versus NP
Lance Fortnow · Princeton University Press eBooks · 2017
This chapter explores two separate paths that led to the P versus NP question. In the end it was Steve Cook in the West and Leonid Levin in the East who would first ask whether P = NP. Science does not happen in a vacuum, and both sides have a long history leading to the work of Cook and Levin. The chapter covers just a small part of those research agendas, the struggle in the West to understand efficient computation and the struggle in the East to understand the necessity of perebor. Both would lead to P versus NP. Today, with most academic work available over the Internet and with generally open travel around the world, there is now one large research community instead of two separate ones.
